cation.

The object of this invention is to provide a plate-holder light-tight, simple in construction, and convenient to be carried around, together with an exposing-case suitable in construction.

Figure 1 is a front view of the exposingcaseand auxiliary case. Fig. 2is a front view of same with holding-case partially removed through the end of exposing-case. Fig. 3 is a perspective of the holding-case. Fig. t is a side view of the holding-case with the plateholder partially removed. Fig. 5 is a view or' the exposing-case and theauxiliary case, with a portion of the auxiliary case cut away to show the rod attached to the holding-case and the holding-case partially drawn into auxiliary case. Fig. 6 is a perspectiveview of the exposing-case, the auxiliary case, and the end door, and the method of attaching them together. Fig. 7 is alongitudinal section of the plate-holder, showing the spring for holding the plate in position.

Similar letters of reference refer to similar parts in the different drawings.

v A is the exposingcase, within which is placed the holding-case B, and in this holding-case is placed the holding-slide C. The holding-slide C holds the glass plate, and is made with grooves in the edges for holding it, and the interior part between the edges is cut away part of the distance, leaving the projection D. The end of this projection D is turned upward slightly, see E, Fig. 7,) to form a spring for holding the plate in position,'thus making the frame of the plate-holder and the spring for holding the plate in position out-of one and the same piece, which enables me to use a thin space for the plate-holder and spring.

The holding-case B is made of any suitable material, open at one end and closed at the other. (See Fig. 3.) In the closed en d is in- 5o serted the screw F. The plate-holder, with the glass plate, is placed within the case-holder B through the open end,with the cross-head G of the plate -holder itting snugly against the open end of case-holder B. Thus is the glass plate placed within an inclosure that is absolutely light tight. In Fig. 7 is shown the cross-head G of the plate-holder. rIhe sides of the case-holder tit snugly against the shoulders b and c.

Vhen the glass plate is placed within the case holder, as above described, the caseholder is placed in the exposing-case A through one end, as shown in Fig. 2.

' I, Figs. 1, 2, and 6, is a door, which closes against the end of exposing-case after the holding-case is placed in position, which further precludes any light from coming into the presence of the glass plate.

J is the auxiliary case, open at one end and hinged to the exposing-case A at the open end by hinges cf, Fig. 4;

K is a rod passing through the closed end of the auxiliary case, and terminating in the interior with a recessed end having a screw cut therein. (See L, Fig. 6.)

Figs. 1, 2, and show the exposing-case and the auxiliary case in the saine plane and locked by the strap and pins M and NN. The exposing-'case is now placed on the camera, and to remove the holding-case B so as to expose the glass plate to the face of the lens in the camera, the recessed end of the rod K is screwed onto the screw F inthe closed end of the holding-case B, and on withdrawing the rod the holding-case B is drawn into the auxiliary case J. (See Fig. 5.) In this construction I entirely land absolutely exclude all light from the presence of the dry-plate, excepting what passes through the lens. and distinct negative can be taken without dangerof its being fogged by cross-light.

By using the holding-caseB, constructed as herein shown, much less room is taken up thauin the old form.

I am aware of Iatent No. 249,181 and the construction therein shown; but this is not my construction, nor does it work in the same way.

I claim- 1. As an articlev of manufacture, the holding-case B, provided with the plate-holder C,

2. The zuixiiiury euse J, in eombinution with :u1 exposing-ease, for the purpose of zuording Y u dark Chamber for the ease B to be drawn into, :is and for the purpose shown.

3. The rod l, in combination with the auxiliary ease J und the 'holding-euse B, for the purpose of drawing the holding-ease B into the auxiliary euse J, substantially us shown.
